#Publish Today, we have VMware hosts configured to round-robin over all the paths to the volume. We're quite happy with this because there is only theoretical performance benefits to using the preferred node in most scenarios. However. With SVC stretch cluster, we have the scenario where a volume is available via two nodes, one on each site, and is being accessed by two hosts, one on each site. And we really want the host on site A to use the node on site A, and the host on site B to use the node on site B. The way we'd do this, agreeing with the suggestion in the RFE, is by having SVC report a different preferred node for the volume depending on who was asking. Today, SVC does not know it is in a stretched configuration: it does not know what hosts are where etc. If we had this feature then we would really benefit from having VMware understand our ALUA state. So, we think that the ALUA/VMware qualification work would fit best as part of making SVC stretched-cluster aware. This would be part of a future "stretched cluster enhancement" bundle item on the roadmap that we are looking to prioritize but it will not likely be in this or the following release cycle. I'll continue to keep this RFE active so that others might comment on it and provide further input.
Agreed with the RFE - I was going to submit the same request when I saw this.

#Publish I have discussed this with development and will size and evaluate priority in the coming weeks.
